Identification
"easily distinguished from other Cryptinae genera by the median dorsal carina of first tergite, strong at least in front of spiracle; prescutellar transverse groove with a strong median longitudinal carina; truncation of hind tibia approximately transverse with spurs inserted at apex; lower tooth of mandible slightly to distinctly shorter than upper tooth; and hind edge of mesoscutum with a transverse break just in front of the prescutellar groove (Townes 1970, Luhman 1990)." -GONZÁLEZ-MORENO 2010
Life Cycle
Species of this genus oviposit in sawfly cocoons. Bob Carlson's comment here.

Hosts are mostly sawflies of Hymenoptera Diprionidae, Tenthredinidae and Argidae (Luhman 1990), but also Lasiocampidae, Pyralidae and Tortricidae moths and other parasitoids such as Braconidae (Yu et al. 2005).
